Will you soon be able to play Fortnite normally on the pc with the ps5 controller, like now e.g. With the X-box one controller?
No you will not.
Sony Playstation controllers are generally not compatible with Windows computers.
Sony blocks the controllers, so you are forced to stay on their platform. So they want to pull the money out of your pocket.
The Xbox controllers are and will remain the best controllers for Android, Windows, MacOS, iOS and Linux.
A little remark:
All features of the Playstation 5 controller can't be used!
Example: The adaptive triggers are only compatible with the cheap Playstation 5 consoles.
But little question… Why can I do that with the Ps4Controller?
Sure it's possible
It depends on which game you are using and what you installed it with
